There are no reports of full endoscopic approach for midline vermian pilocytic astrocytoma by suboccipital endoscopic key hole approach and there are only one previously study about use of fuorescein in benign neuroepithelial primary brain tumors. We reported a patient treated previously in other centers for upper vermian paraventricular pilocytic astrocytoma that was operated by suboccipital full endoscopic approach using a high-dose fluorescein-sodium (20mg/kg) with a standard could light for resection. We concluded that the suboccipital key hole endoscopic approach is a good alternative for vermian and IV ventricle tumors in selected cases of partial vermis absent caused by previous surgeries or tumors cysts extension and offers a unique and detailed anatomic perspective. High doses of intravenous fluorescein-sodium seem to be a useful intraoperative technique for delineation of pilocytic astrocytoma. Highlights Cerebellar pilocytic astrocytoma represent a benign tumor Minimally invasive surgery constitutes a good alternative in selected patients. Intravenous fluorescein – sodium improves delineation and resection of the lesion.
